19. James P. Hackett

Interim Athletic Director

University of Michigan

James Hackett retired from Steelcase Inc. in early 2014 after nearly two decades as president and CEO. That tenure included painful decisions, notably a reorganization that cost 12,000 jobs but is credited with ensuring the company's long-term survival.

He wasn't retired for long. The Columbus, Ohio, native was named in October to step in as the University of Michigan's interim athletic director after the midseason departure of David Brandon (No. 33).
